The relational model for database management is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, where all data is represented in terms of tuples, grouped into relations. Entity relationship diagram, ERD, is a diagram that displays the relationships of entity sets stored in a database. In other words, ER diagrams help to explain the logical structure of databases. ER diagrams are created based on three basic concepts: entities, attributes and relationships.

Also is that, not normal for bookkeeping measures, non-monetary information are estimated in numerous ways, there is no shared factor. Assessing execution or making compromises between ascribes is troublesome when some are named on schedule, some in amounts or rates and some in subjective ways. The third issue is an absence of causal connections with the fourth being the absence of factual dependability – regardless of whether an action really addresses what it indicates to address, rather than irregular \”measurement error\”. Lastly albeit monetary measures are probably not going to catch completely the many elements of hierarchical execution, carrying out an assessment framework with such a large number of measures can prompt “estimation deterioration”.
The Balanced Scorecard (see Appendix two) is a straightforward framework that drives us to inspect how every one of the segments act in every one of the squares (reason, assets, empowering process, future). All the while, you can likewise evaluate individual execution against similar standards. It not just summarizes what we need to do, it does it in a way that guarantees everybody in the organization knows what they are attempting to achieve and what is significant in taking care of business, this is obviously distinguished in Appendix two, notwithstanding, the decent scorecard writing gives little conversation of the scorecard\’s job in pay choices, in spite of the way that most of adopters utilize the scorecard for this reason (Towers Perrin, 1996).
